Peterson was in Orlando when he died -- preparing for the Olympia competition -- which kicks off Wednesday.

The cause of George's death is not yet clear, but his coach and close friend, Justin Miller -- who found Peterson deceased -- provided additional details on his death.

Miller says Peterson was in incredible spirits the night before he died ... and was pumped for the upcoming competition.

However, the next day, Miller says GP wasn't responding to texts or phone calls ... so he became worried, and went to George's hotel room.

Inside, tragically, Peterson was face down on the floor, cold. Still, Miller, desperate to help his friend, called 911 and was instructed to do CPR.

Unfortunately, Peterson -- who likely passed several hours earlier -- could not be saved.

Peterson won the Classic Physique competition at the 2019 Arnold Classic.
